This week on the podcast we're talking about AT&T's crappy new smartphone upgrade plans, the awesome secret stuff you can get on Monoprice, and how to survive an Airbnb disaster. We're also answering your questions about Mac Wi-Fi issues, MP3 tagging, and transforming go bags.

How Can I Avoid Getting Screwed on Airbnb? With Airbnb becoming illegal in New York, other cities considering the same, and horror stories of bad hosts, you might feel too scared to rent. These circumstances come along pretty infrequently, and handling them takes very little effort if you know what to do.

Questions and Answers

Marianna asks, "There are over 25 Wi-Fi networks in my apartment building. EVERY single time I want to get on the internet, which with Lifehacker, is very often and for long periods of time, I must go to the WiFi icon on my MacBook and select my own network instead of whatever other one it selected. I've scoured LH (and Google) and cannot find a satisfactory answer to making my network the default. I'd eliminate the entire list if I thought I could. I have selected it in Network Preferences and moved it to the top of the list, but it doesn't last long. Got any bright ideas?"

Yes! You probably need to reset your network settings. Alternatively, it could be an interference issue. Make sure your Wi-Fi network doesn't have the same name/SSID and you've chosen the best wireless channel. You may also solve the problem by creating a new location in your Network settings (it's up at the top).

Juan writes, “I've been looking everywhere for a decent bag that functions as both a messenger and a backpack, preferably a bag that would hide the backpack straps when not needed, and a bag that is big enough to haul a Chromebook, tablet, a book, and other office items. I work in an office close to home so it allows me to drive, or walk (an hour walk), or ride my bike (about 20 minutes). Are there any bags out there that would do the job?”

How Do I Submit a Question?

Please keep your questions as brief as possible. This means about 3-5 sentences for emails and 30-60 seconds for calls and videos. Your questions can be specific, but broader questions are generally better because they'll apply to more people. For example, "how can I breathe new life into my old PDA?" is much better than "what can I do with an old HP iPAQ 210?" Either way, we look forward to hearing from you!
